Great question! The timezone settings within the interface is meant for internal agents and showing the time of updates within tickets. I'm not aware of a plan to push that setting out to Help Centers as well, so for now it will remain a custom JavaScript solution.

Any time you go into an article, make a change, and then update the article, it should update the time. If you weren't seeing it right away, it was probably because the browser cache hadn't refreshed yet. Doing a hard refresh on your browser will usually take care of this.
